Feedback of Samsung LN52A750 52-Inch HDTV

I am planning to buy Samsung LN52A750 52-Inch HDTV from one of my friend. He bought this TV in Jan09 with extended warranty 1 + 4year. He is asking $1800. Is it worth?
I dont have any idea should i go for this or not?How much i should offer him?

If your going to buy from Best Buy, wait till the end of the month. They have a quota to fill and they are willing to negotiate on a price. The last day for them is always on a Saturday. Example: this month it will fall on 7/4/09 I know this from experience (i made a recent purchase this way).
